GROUNDWATER USE    Water use figure

  • From 1979 to 2005, total water use in Florence County has increased from about 280,000 gallons per day to about 540,000 gallons per day to 2000.  Total water use in 2005 decreased to 320,000 gallons per day.*
  • The increase and decrease in total water use is due primarily to domestic use.
  • The proportion of county water use supplied by groundwater has remained at 100% except in 1995 when it was 98%.*
  • Water use in Wisconsin is generally estimated for the following categories:
    • Domestic
    • Livestock
    • Aquaculture
    • Irrigation
    • Industrial
    • Commercial
    • Public use and losses
    • Thermoelectric or mining*

* Thermoelectric and mining data are not considered in water-use tables or figures on this web site. Thermoelectric-power water use is the amount of water used in the process of generating thermoelectric power. The predominant use of water is as non-contact cooling water to condense the steam created to turn the turbines and generate electricity.



  • Wisconsin has abundant quantities of high-quality groundwater, but once groundwater is contaminated, it's very expensive and often not technically possible to clean.
